IMPROVEMENT IN UNION-JOINTS FOR ARTESIAN-WELL BARS.

Specification forming part of Letters Patent No. 222,914, dated December 23, 1879; application filed November 14, 1879.

To all whom it may concern:

Be it known that I, FREDERICK H. KURO- ZYN, of the city of Mexico, Mexico, have invented certain new and useful Improvements in Union-Joints for Artesian-Well Bars and other purposes, of which the following is a full, clear, and exact description, which will becoming disconnected, either when used for purposes such as boring Artesian wells, where a long continuous straight line is required, or for the rigid connection of shafting or other analogous purposes to which the same may be I applied.

Heretoforc in boring Artesian wells great difficulty has been experienced, first, by the friction produced from the wabbling of the rod, owing to the connections being made imperfectly and consequent zigzag form, which the rod so connected naturally takes, making it practically impossible to bore a straight hole; and, secondly, in the accidental disconnecting of the sections when reversing the turn of the rod in loosening the bar or withdrawing the same, all of which difficulties are overcome by my invention.

In the case here presented, on the extremities of each sect-ion of rod there is a square head or nut, A, and neck B, which fits snugly in corresponding recesses 0, made and provided for the same in the extremities of the union-block piece D. The said union'block, being preferably made of cast metal, has an attachable and detachable section, E E,'on alternate sides of each of its ends, forming a convenient mode for the insertion of the ends of the bars in making a connection, or for the removal of the same when necessary, as well as forming a safe and secure mode of holding and locking the same in position. The said detachable sections have a V or chisel shaped lug or tongue, F, at their base, which fits in a corresponding groove, indent, or mortise, Gr, in the union-block, and have a neck or flange, H, over which the cap-nuts I'I engage. Upon each end of the aforesaid rods, immediately above the necks B, a screw-thread, J, is out on the bar, and upon which the cap-nuts I I travel.

It will here be observed that when the square-threaded ends are inserted in their respective positions in the recesses of the unionblock, and the removable sections fitted or set in their respective places, by simply tightening the cap-nuts which fit over a. neck or flange on the extremities of the union-block and detachable sections thereof, the whole will be clamped together, forming a true linejoint of equal strength and stifl'ness to that of a solid bar; and, furthermore, in having the ends square-headed and fitting snugly in position, it enables the bar to be turned in either direction, or to be used for rock-drilling or pounding without the possibility of its beconn ing disconnected or bruised at its joints, thereby enabling the bars to be loosened or taken apart with easewhen necessary.

1 do not limit myself to the sole and only use of forming a union-joint for Artesian-well borers, as I also desire and propose using the union-joint as above described for line-shafting and such other analogous purposes to which the same can be advantageously applied.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a union-joint for Artesian-well bars, shafting, and other purposes where'a continuous straight line is required, the heads A and cap-nuts I on the bars, in combination with the union-block D, recesses O, and detachable side pieces, E E, with flange H and tongue F, all operating together in the manner and for the use and purpose substantially as described.
